INJECTOR AND INJECTING ARRANGEMENT FOR STORAGE CONTAINERS Jacques Bolsey, New York, N. Y.

Application February 14, lil ld'ser'i'al No. 647,646

It is an object of my present invention to provide an injecting device which is always ready for operation and can be operated in an extremely simple way. 1

It is a. further object of my present invention to provide an injecting device which can be operated with one hand, without touching the injecting device itself.

, Still another object of my present invention consists in an injecting device which injects a fluid into a vial or the like when the same is pressed against the dispensing head of the injector.

Still a further object of my present invention consists in an injecting device without closure means which have to be removed before and replaced after each injecting procedure.

With the above objects in view, my present invention mainly consists of an injecting device comprising in combination an injector container containing the fluid to be injected, an injector headmounted on this container, an injector nozzle arranged in this injector head, and; means forcing fluid from the above mentioned injector container through the injector nozzle whenever pressure is exerted against the injector head. As will be explained farther below in detail, this pressure can be exerted by an inlet member forming part of the vial or other container to be filled. Thus, it is possible to flll'this vial simply by holding'it with one hand and pressing the inlet member forming part thereof against the injector head of the injecting device placed upon a stationary support, e. g. a table.

In accordance with a preferred embodiment of I my present invention, I construct the injecting device so that either the injector head mentioned above or the bottom of the injector container are movable into the container itself, so as to decrease the volume of this container; such decrease of volume forces fluid to flow from this container through the injector nozzle and into a vial held against the outer end of this nozzle.

I have found it particularly advantageous to provide my injecting device with an outward projecting membrane serving as the bottom of the container. Bending of this membrane inwards into the container will result in decrease of the volume of the same and force the fluid through the nozzle. It is evident that such bending of the membrane serving as the container 11Clainis. (craze-65.5)

bottom can be'easily attained by placing the entire injecting device on a stationary support in such a manner that the container rests on the outward bent membrane bottom and then pressing the entire device against the support. This will result in inward bending'of the membrane bottorn'and ejection of fluid through the nozzle in the container head. j

Itis evident that the downward pressure necessary for inward bending of the membrane bottom can be obtained by' holding the vial to be filled and pressing itagainst the'inje'ctor head at the top of the injector container. This will result in downward movement 'of'the entire injecting device, inward'bending'o'f its membrane bottom and ejection of fluid through the nozzle in the con-' tainer head; this'fluid will be directly injected into the vial placed upon the container head.

The novel'ieatures'which' I consider as characteristic for "my invention are set'forth in particular in the appended claims. The invention itself, however, both as to itscons'truction and its method of operation, together with additional objects 'and'advantages thereof, will be best understood from the following description of specific embodiments I when read in'connection with the accompanying drawings, in which: "Fig. 1 is an elevational section of an injecting device accord'ing' to my present invention;

Fig. 8 is an elevational cross section of still another modified embodiment of the injecting device shown in Fig. 1-; and

Fig. 9 is an elevational cross section of still another modified embodiment of the injecting device shown in Fig; 1. i The injecting device shown in'Fig. 1 consists of an injector container It] being open at its't'op II, and provided with a flexible membrane bottom I2 which will be described below in detail.

The open top II of container III is closed by a container head I3 which tightly fits into the cylindrical wall portion I4 of the container I so as to prevent escape of air and fluid contained in the container between the container head I3 and the cylindrical wall portion I4 surrounding the same. r

The container head I3 is provided with a depression I5 for receiving the inlet member I6 of the vial II partly shown in Fig. 2. This depression I5 is connected with the inside of .container I0 by the tubular member I8 whichreaches at its top indicated by I9 into depression I5. The bottom end 20 of this tubular member l8 is near the membrane bottom I2 of container Ill.

The flexible membrane bottom -I2 mentioned above is secured to the circular edge 2| of .container I0 so as to project downward beyond this edge. This bottom I2consists of flexible material so as to be adapted to be pressed inward into the position indicated by dotted lines 22 when pressure is exerted against itin direction of arrow 23. It is evident that such pressure can be exerted not only by pressing directly against the bottom, but also by placing the entire container on a stationary support indicated by numeral 24 and pressing in direction of arrow 25 against the container head I3.

It is also evident that compression, '1. e. upward bending of the flexible membrane bottom I2 into the position indicated by dotted lines 22 will result in decrease of the volume of container II) which, in turn, will force fluid 26 contained in this container ID into the tubular member I8 as indicated by arrow 21 andthrough this tubular member I8 into depression I5.

The fluid ejected through the tubular member I8 into depression I5 will be injected directly into the inlet opening 28 provided in the bottom of the inlet member I6 forming part of the vial II shown in Fig. 2. This inlet opening is closed by a valve ball 29 pressed by valve spring 30 against seat 3 I. It is evident that if the valve spring 30 is weak enough, the pressure of the fluid 26 ejected through the tubular member I8 will force the valve ball 29 in direction of arrow 32 against action of valve spring 30 and thus free the opening 28 for passage of fluid 26 into vial II.

It should be stressed that the downward pressure which has to be exerted in direction of .arrow 25 so as to bend bottom I2 into its position indicated by dotted lines 22 can be obtained by holding via-l -I-I, inserting its inlet member. I6 into depression I5 and pressing the vial downward in direction of arrow 25. This will result in ejection of fluid through the tubular member I8 which will, in turn, be injected directly into the inlet opening 28 of the vial I1 while the same is pressed downward.

The relatively simple embodiment shown in Fig. 1 is satisfactory in many cases, particularly if a small amount of fluid has to be injected and if the bottom end of the vial completely fits into the depression I5 so that the entire fluid ejected through the tubular member I8 is injected into the vial. However, in the event that the container head I3 has to be pressed downward several times and the vial does not fit perfectly into depression I5 in the container head 13, it is advisable to provide separate means enabling the return of the fluid from depression I5 into .container I0.

.as shown in Fig. 3.

In Fig. 3 I have shown a preferred embodiment of my invention which is equipped with separate means for return of the fluid into the container.

In this embodiment, the container head 33 is' screwed as indicated by numeral 34 into a screw threaded cylindrical portion 35 of container 36. The membrane bottom 31 of container 36 is pressed downward by means of spring 38 arranged between this membrane bottom and the face 39 0f the container head 33.

A tubular hole is provided in the container head 34 and in this hole a slidable tubular member 40 is arranged. This slidable tubular member 40 is pressed upward in direction of arrow 4| by means of the relatively weak spring 42 arranged In order to prevent this tubular member 40 from moving higher than shown in this figure, projecting pins 43 are secured to it; these projecting pins abut in the position shown against the container head 33.

In accordance with my present invention, I provide in the wall of the hole through which tubular member 40 is passing several grooves 44 through which fluid can flow back from the depression 45 into the container 36. In order to prevent fluid from passing through these grooves 44 from container 36 into the depression 45 during operation of the device, I provide at the top of the slidable tubular member 40 a mushroomshaped head 46 which, when pressed downward, completely closes the upper open ends of the grooves 44.

This injecting device is operated in the same wayas the injecting device shown in Fig. 1: The only difference is that when vial I! is inserted with its inlet member I6 into the depression 45 and pressed downward in direction of arrow 4.1, the bottom .of the vial will first press against the mushroom-shaped head 46 of the tubular member 40 and press the same downward until the upper ends .of the grooves 44 are closed and only then will the membrane bottom 31 of the container 36 be compressed in the same way as described above in connection with Fig. 1.

Thus, during the .actual injection rocess the grooves 44 are closed. When the injection process is finished and the vial to .be filled is lifted in direction of arrow M, the spring 42 will move the tubular member 40 and its head 46 into the position shown in Fig. 3, thus freeing the grooves 44 and enabling return of fluid from the depression 45 into the container 35.

The embodiment shown in Fig. 6 is similar to the one shown in Fig. 1. The only difference is that the .container head 48 is screwed into the uppercylindrical portion 49 of the container 50, that a spring 5I ls providedi-n the same way as shown in Fig. 3, and that a separate return hole 52 combined with a spring valve 53 is arranged in the container head 48. The spring 54 .forming part of the spring valve 53 is so weak that the vacuum created in container 50 during return of the membrane bottom 55 from its compressed into its expanded position is sufficient to open the spring valve 53 and enable return of fluid from the depression 56 in the container head 48 into the container 50.

The modified injecting device shown in Fig. 5 is also similar to the above described injectors. However, it is equipped with a spring valve 51 arranged between the stationary tubular member 58 and the outlet nozzle 59 leading into the depression .60 in container head BI. This spring valve 51 prevents the fluid from flowing back from the vial II to be filled into the container II is not bent outward and is not flexible.

62, if at the end of an injection period the spring operated valve ball 29 does not close immediately the inlet opening 28 at the bottom of vial I1.

Furthermore, the modified injector'shown in Fig. 5 is not equipped with any closing means of the type shown in Fig. 3 or valve means of the type shown in Fig. 6 for-the conduits 63 provide for return of fluid from depression 60 into container 62; instead of such closing or valve means. A stationary felt ring 54 is arranged as shown in this figure, permanently pressing against the open ends of the mentioned conduits 63. This felt ring on the one hand prevents escape of fluid through the conduits 63 during the injection periods and on the other hand absorbs the fluid returning through these conduits 63 between these injection periods.

The modified injecting device shown in Fig. I is similar to the injectors shown in Figs. 5 and 6: it combines a spring valve 51 arranged between the stationary tubular member I55 and the outlet nozzle 56, with valve means for closing the lower ends of the conduits 63 provided in the container head 6!. These valve means at the lower ends of the conduit 63 serve the same purpose as the spring valve 53 in the injecting device shown in Fig. 6. The only difference is that these valve means consist of a valve washer 61 pressed by the weak valve spring 68 against the bottom face of container head 6|. This valve spring 88 abuts, as shown, against the ring 69 secured to the stationary tubular member 65. In this embodiment, the vial I! is shown in operative position, pressing against the container head 6 I.

The injecting device shown in Fig. 8' differs in various respects from the above described embodiments of my present invention: The main difference is that the bottom 10 of the container It does not have an effect upon the injecting process. The pressure necessary for ejecting fluid through the stationary tube 12 is obtained by provision of a slidable container head I3 which can be pressed downward in direction of arrow I4 against action of spring 15. This slidable container head slides in a cylindrical cylinder 76 arranged inside of the container II and provided with openings II communicating with the space within the container I I.

This injecting device is operated by placing the lower end of vial I'I shown in Fig. 2 into the depression I8 and pressing it downward, thus moving the entire container head 13 in direction of arrow 14. This results in forcing of fluid from cylinder I6 through the openings 11 into the space within container I I; this, in turn, results in increase of pressure within this container and ejection of fluid through the tubular member 12 into depression I8 and injection of this fluid into the inlet opening 28 of vial II.

In Fig. 9 I have shown still another embodiment of my new injecting device. The same is very similar to the one shown in Fig. l. The'only difference is that the flexible membrane does not form the bottom of the container I0 but is a'rranged at the top of the container surrounding the container head l3.

- As clearly shown, the bottom 80 of container I0 is absolutely rigid and a separate membrane BI is secured with its outer edge to the top edge of the side wall of container l0 and with its inner edge to the container head I3. It is evident that pushing down of container head I3 will result in ejection of fluid through the nozzle in the container head.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of injecting devices differing from the types described above.

While I have illustrated and described the invention as embodied in injecting devices for injecting fluids into vials, particularly perfume containers, fountain pens and cigarette lighters, I do not intend to be limited tothe details shown, since various modifications and structural changes may be made Without departing in any way from the spirit of my invention.

Without further analysis, the foregoing will so fully reveal the gist of my invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
